有道云笔记自动签到

主体步骤

1. 笔记本装fiddler；猎豹WiFi开热点；

2. 手机连接热点，WiFi设置代理-手动-主机为192.168.1.1，端口为8888；

3. 手机浏览器访问fiddler代理ip+端口，如猎豹WiFi是192.168.191.1:8888，安装fiddler证书到手机；否则app是不给联网的。

4. 抓app的包。

5. 分析app登录、签到时都干了什么。

 具体实施

好，假设你已经做好了准备工作。

（1）第一步，device_open

当有道云笔记app打开时，app访问device_open，fiddler抓到的包：
注意返回的delusers数组，删除用户？怪吓人的。

上图是POST请求，下图是服务器返回（下同）。

 

 

（2）第二步，login

如图，重点是请求时发送的usertoken，这个是app内部产生的。这个token变化的频率是？

经测试，退出app后再次打开，此token没有变化。或许是每天变化一次。后面测试。

服务器返回的就是set-cookie了。usertoken不变，cookie就不用变。

 

 

（3）login后的很多请求使用cookie

在这之后app的自动请求已有LOGIN=true的cookie了。

 

（4）点击签到访问服务器 checkin 方法

点击签到按钮，请求checkin method

 

返回签到是否成功，签到得到的空间等等。

今天打开笔记签到，user token 没变，cookie也没变。 

 

2016/05/11 13:44

user token 和 cookie 依旧没变。

由此推论，只要app运行的环境不改变，发送给server的token不会变，返回的cookie不会变。

退出账号后再次登录，user token会改变。仅退出app（登录状态是保留的），下次打开app自动登录，user token 不改变。

 

好，下面上代码。关键是main函数中的三个方法，模拟了你打开app-点击签到按钮的这个过程。

程序中有的参数需要自己抓包然后放进去。
